Abstract
A reciprocating pump system includes a fluid end that includes plungers configured to be reciprocated within respective bores in a body. Dynamic packings in each of the bores are configured to be energized into dynamic sealing engagement around respective plungers against pressure from a pressure side. Dynamic packing nuts are engageable with atmospheric sides of respective dynamic packings opposite the pressure side to energize the respective dynamic packings. Static packings in each of the dynamic packing nuts are configured to be energized by mechanical force into static sealing engagement around respective plungers against pressure from a pressure side. While the plungers are reciprocating within the bores, the dynamic packings are energized by the dynamic packing nuts and the static packings are deenergized. When a plunger is not being reciprocated, the respective static packing is energized into static sealing engagement with the respective plunger.
